There are over 2,000 different kinds of tea in the world. This huge number of teas can be divided into five categories: green tea, black tea, white tea, oolong tea and herbal tea. All these types of tea come from the same plant, camellia sinensis. Different teas are made by doing different things to the leaves of the camellia sinensis plant.

People have felt for a long time that green tea has positive effects on our health. Recently, many studies have been done to try to prove these claims. These studies have shown that green tea can reduce heart disease, some kinds of cancer and improve brain functioning. But these studies have only been done on animals. There have also been many studies on green tea's effects of humans. Scientists have studied green tea's effect on weight loss, cancer, heart disease, Parkinson's disease and glaucoma. The results of these studies have shown that green tea might help in treating or preventing these diseases. More research needs to be done to prove completely that green tea can or can't help in treating these diseases.

Whether you believe that it can cure all your ills or not, green tea is very popular now and will most likely continue to be popular in the future.
